    FTP delays answering zOS client

    807559
      I have a Solaris 9 FTP server serving zOS jobs

      Sometimes, the FTP client outputs the messages:

      Connecting to: solaris9.ftp.server xxx.xxx.xxx.xxx port: 21.
      Connection to server interrupted or timed out.
      Server not responding, closing connection.
      FTP Return Code = 10000, Error Code = 00009

      I used snoop to trace the connection, with the following:

      130 8.29945 yyy.yyy.yyy.yyy -> solaris9 FTP C port=3776
      131 0.00015 solaris9 -> yyy.yyy.yyy.yyy FTP R port=3776
      132 0.28311 yyy.yyy.yyy.yyy -> solaris9 FTP C port=3776
      133 60.00031 yyy.yyy.yyy.yyy -> solaris9 FTP C port=3776

      138 0.00008 10.135.150.141 -> sappvfci FTP C port=3776

      I'm thinking the FTP is spending more than 60 seconds to reply and the client is closing the connection... is this correct?

      Is there a way to increase the time of in.ftpd response ?
